Mattress Buying Guide Australia: Memory Foam Mattress, King Size Mattress & Queen Size Mattress Explained
By Clark Rubber | 11th November, 2026
A good mattress is one of those purchases that quietly affects everything - how you feel when you wake up, how well you recover after a long day, and even how much energy you have.
In Australia, mattress choices can feel overwhelming. Memory foam, different sizes, varying firmness levels - and then the big decision between a queen and a king size mattress.
This guide breaks it down in a practical way so you can choose what actually suits your sleep, your space, and your lifestyle - not just what looks good on paper.
Types of Mattresses
Memory Foam Mattress
A memory foam mattress is designed to contour to your body shape, offering support where you need it and cushioning where you don’t. For many sleepers, this creates a more “settled in” feel compared to traditional spring mattresses.
People often choose memory foam because it can help reduce pressure points, especially around shoulders, hips, and lower back. It’s also a popular option for couples since movement is less likely to transfer across the bed.
In real-world terms, it suits:
- Side and back sleepers
- Light to medium movement during sleep
- People wanting a more cushioned feel
- Shared beds where motion transfer matters
For a practical option, the Dreemi Mattress Queen is designed for everyday home comfort with memory foam support.
Memory Foam Mattresses (Variants & Sizes)
Memory foam mattresses aren’t one-size-fits-all. They come in different dimensions depending on your room and sleeping needs, from single beds through to king size setups.
Common options include:
- Single: ideal for kids, guest rooms, or compact spaces
- Double: suitable for solo sleepers wanting extra room
- Queen: the most common balance of space and practicality
- King: maximum space for couples or restless sleepers
Choosing the right size is often less about “bigger is better” and more about how much room you actually have - both in your bedroom and in your sleeping habits.
The Dreemi Mattress Single is a practical memory foam option for smaller spaces or secondary bedrooms.
Choosing the Right Size
The decision between a king size mattress and a queen size mattress is one of the most common choices for Australian buyers.
A queen size mattress is often considered the “standard” for couples. It fits comfortably in most bedrooms while still offering enough space for two people to sleep without feeling cramped.
A king size mattress, on the other hand, gives each person more personal space. It’s especially useful if:
- You share a bed with a partner or kids
- You move around a lot in your sleep
- You have a larger bedroom
- You want a more spacious, hotel-style feel
The trade-off is space in the room. A king mattress can dominate smaller bedrooms quickly, so measuring your space before deciding is important.
Think of it as a balance:
- Queen (1520mm x 2030mm) = practical and versatile
- King (1820mm x 2030mm) = spacious and comfort-focused
Benefits of a Memory Foam Mattress
Memory foam mattresses are popular for a reason - they tend to feel more supportive and adaptable than many traditional mattress types.
Some of the key benefits include:
- Pressure relief: Helps distribute body weight more evenly
- Comfort support: Adapts to different sleep positions
- Motion isolation: Reduces disturbance from a partner moving
- Durability: Holds shape well with regular use
- Adjustable base compatibility: Works well with many adjustable bed setups
For couples, one of the biggest practical advantages is reduced movement transfer. If one person gets up or shifts during the night, the other is less likely to feel it.
This makes memory foam a strong everyday option for shared beds.
Best Memory Foam Mattress Australia
When choosing a memory foam mattress in Australia, it helps to focus less on marketing terms and more on how the mattress is built for real use.
Things to look for include:
- Firmness that matches your sleep preference
- Support that feels consistent across the surface
- A size that suits both your room and sleeping habits
- A feel that balances comfort and structure
The “best” option is usually the one that feels supportive without being too soft or too firm for your body.
If you’re unsure, starting with a queen size memory foam mattress is often a safe middle ground for most households.
Accessories for Better Sleep
Sometimes the mattress is only part of the picture. The right accessories can make a noticeable difference in comfort and sleep quality.
Useful add-ons include:
- Mattress toppers
- Memory foam or supportive pillows
- Mattress protectors for hygiene and longevity
- Pillow protectors for everyday freshness
A few practical options:
The best memory foam mattress depends on your comfort preference, room size, and whether you sleep alone or share a bed. Look for a balance of support, comfort, and suitable sizing.
Memory foam can help with pressure distribution and support by contouring to the body, which some sleepers find more comfortable for back support.
A queen size mattress suits most bedrooms and couples comfortably. A king size mattress offers more personal space but requires a larger room and more floor space overall.
